GEORGE W. HUGHEY, OF SPRINGFIELD, MISSOURI.

WRENCH.

Application filed November 30, 1915.

Z '0 all whom it may concern:

Be it known that I, GEORGE IV. HUGHEY, a citizen of the United States,residing at Springfield, in the county of Greene and State of Missouri,have invented new and useful Improvements in lVrenches, of which thefollowing is a specification.

This invention relates to wrenches, and one of the objects thereof is toprovide a simple, cheap and eflicient device capable of rapid andreliable adjustment.

Another object of the invention is to construct a wrench with a rigidjaw having a longitudinally slotted shank, to arrange a slidable jawupon the shank, and to pro vide the slidable jaw with a pivoted hingedlocking part which may be swung to frictionally engage with the inneredges of the bifurcated portion of the wrench and to positively lock thejaw upon the shank.

With the above and other objects in view, the improvement resides in theconstruction, combination and arrangement of parts set forth in thefollowing specification and falling Within the scope of the appendedclaims.

In the drawings: Figure 1 is a view in side elevation of a wrenchconstructed in accordance with the present invention, Fig. 2 is acentral longitudinal sectional view through the same, Fig. 3 is atransverse section through the sliding jaw, Fig. 4.- is a similarsection taken through the shank and through the locking block of thesliding jaw, Fig. 5 is a perspective view of the sliding jaw, Fig. 6 isa similar view of the looking block.

The wrench, in the form shown in Figs. 1 to 6, has its shank 1 providedwith a laterally extending head 2 forming the same with jaws disposedone to each of the opposite sides of the shank, and one of the said jawspreferably has its working face toothed, as indicated by the numeral 3.

The shank 1 is slotted longitudinally, providing the same with a pair ofspaced bars 4P4, and the inner edges of these bars are provided withteeth 5.

The numeral 6 designates a handle which is removably secured to thereduced end of the shank, and the removal of this handle permits of thearrangement 4 on the said shank of a slidable jaw 7. The slidable member7 comprises a head member having spaced slots or passages 8-8 throughwhich bars 4- 1 of the shank 1 pass, and the said member is provided atthe opposite sides of Specification of Letters Patent.

Serial No. 64,322.

the mentioned jaws with heads which are adapted to co-act with the jawsprovided by the head 2. One of these jaws has transs 'erse teeth 9 whichare adapted to co-act with the toothed jaw 3 of the head 2.

The end of the member 7 opposite that provided with the jaws iscentrally formed with a lug 10 which is adapted to be received betweenspaced ears 11-11 provided upon a locking block 12.

The numeral 18 designates a pintle which passes through the cars 11 andthe lug 10 whereby the block 12 is hingedly secured to the slidingmember 7. The block 12 has its sides provided with teeth 14- which areadapted to engage with the teeth 5 of the arms 4 of the shank 1, whenthe block is swung between the said arms. In this connection it shouldbe stated that the teeth of the bars as Well as the teeth of the blockare arranged at a curve, so that the said block may be swung to eitherside of the shank 1 when the member 7 is to be slid upon the said shank.Also preferably the space between the teeth, at the outer sides or facesof the memberselis slightly widened to permit of the ready engagement ofthe {)eeth of the block between the teeth of the ars.

In order to retain the block between the bars 4 to hold the sliding jaw7 in an adjusted position, I provide a catch member including a centralportion or stem 15 which passes transversely through an opening in theblock and which has its ends provided with spring arms 1616 which are ofa width sufficient to be brought over the side or faces of either of thebars 4-. The arms 16 are constructed preferably of spring material andthe ends of both are preferably flared outwardly and one of said ends isprovided with a handle 17 whereby the catch may be readily actuated.

Having thus described the invention, what I claim is:

1. A wrench h. ving a rigid jaw provided the same with spaced bars, theinner edges of which are toothed and the distance between the teeth isgreater at the ends of the teeth than at the central portions of theteeth, a sliding jaw carried by the wrench, a pivoted block on the aw,said block having its edges toothed to engage with the teeth of thebars, a latch for the block comprising a member passing transverselythrough an opening in the block and having its ends provided with springarms of a length to engage with the shank at the opposite sides of itsslots and one of said spring arms being provided with a handle.

3. A wrench having a rigid jaw provided with a longitudinally slottedshank, the inner edges of which are provided with rounded teeth and thedistance between the teeth is greater at the ends thereof than at thecentral portion, a sliding jaw carried by the shank, a pivoted block forthe jaw, said block having its ends formed with teeth to engage with theteeth of the slotted shank and a latch member upon the block operablefrom either side thereof to lock the block upon the shank.

In testimony whereof I affix my signature in presence of two witnesses.
